The code for the data preparation is pasted below:

from traffic.data.samples import tour_de_france

def straight_ratio(flight) -> float:
    return flight.distance() / flight.cumulative_distance(False, False).max("cumdist")

preprocessed = (
    tour_de_france.iterate_lazy(iterate_kw=dict(by="1H"))
    .assign_id()
    .apply_time("5T", straight_ratio=straight_ratio)
    .query("straight_ratio < .5")
    .max_split()
    .longer_than("1H")
    .eval(desc="processing")
)
